6620 Appendix T2

Types, Description, and Use of

Personal Protective Equipment (PPE)

 

 

1.0            Purpose

 

Making the proper decision when identifying the need for and selecting the appropriate type of personal protective equipment (PPE) minimizes the risk of exposure to a hazard issue(s).  Each type has characteristics that provide specific protection. This appendix describes the most common basic, non-specialized PPE used at Jefferson Lab.

 

2.0            Scope

 

This appendix describes types of basic, non-specialized PPE used at Jefferson Lab. These include:

 

·         Hard Hat

·         Safety Glasses w/Side Shields (as needed)

·         Face Shield

·         Safety Shoes

·         Hearing Protection

·         Gloves

·         Knee Pads

·         Proper Work Clothes

 

Basic, non-specialized PPE does not protect against exposure to certain hazard issues (i.e., electricity, welding, oxygen deficient environments, etc.). These hazards require specialized PPE, and often, training in its use. See the ES&H Manual Chapter applicable to a specific hazard issue for specialized PPE requirements.

 

Information within this appendix is provided in coordination with ES&H Manual Chapter 6620 Personal Protective Equipment.

 

3.0            Responsibilities

 

Refer to ES&H Manual Chapter 6620 Personal Protective Equipment for the list of responsibilities associated with this appendix.

 

4.0            Personal Protective Equipment

 

Basic, non-specialized PPE is used to minimize head, eyes, face, feet, hands, knees, hearing, and body injury. The supervisor of a specific work area or a Task Hazard Analysis (THA) determines the need for PPE. The list below describes the basic types of PPE and when to use it.

 

4.1              Hard Hat:

A type of helmet predominantly used to protect the worker’s head from falling objects, impact with other objects, debris, and electric shock.  

 

4.1.1        Description:

·         Hard outer shell that is Type 1 Class E and G – which provides top protection.

·         Shock-absorbing suspension that includes a headband and straps that suspend the shell from 1 inch to 1.25 inches away from the head.

·         Instructions that explain proper adjustment and replacement of the suspension and headband.

 

4.1.2        When to Use:

·         Work involves:  

o   Construction,

o   Activities involving material handling equipment, or

o   Where posted.

 

4.2              Safety Glasses w/Side Shields (as needed) and Goggles

Protection for the eyes from flying objects, particles, chemical splashes, radiant light, etc.

 

4.2.1        Description:  Those used at Jefferson Lab have:

·         Metal or plastic frames,

·         Impact-resistant lenses, and

·         Side shields. 

 

4.2.2        When to Use:  

·         Goggles:

o   Direct-vented: These allow air flow for comfort and to reduce fogging.  Generally, direct-vented goggles are inappropriate for liquid chemical use because the vent ports allow splashed liquids to pass through and they provide no protection against airborne eye irritants (gases, vapors, fumes, dusts, and mists).

o   Indirect-vented: These allow air flow for comfort and to reduce fogging. These are appropriate for liquid chemical use as they protect the eyes from splashes. They do not guard against irritating gases, vapors, fumes, dusts, and mists.

o   Non-vented: These have no vents and are required for operations that produce airborne irritating gases, vapors, fumes, dusts, and mists. They protect against chemical splashes to the eyes.

·         Laser Safety Goggles/Glasses:

o   Protect against specific wave lengths and intensities of laser light. 

o   Are labeled to signify the wavelengths, and optical density that they protect against.

 

4.3              Face Shields:

A device used to protect wearer's entire face (or part of it) from hazards such as flying particles, chemical splashes, sparks or metal spatter. They do not provide adequate protection against impact hazards and are used with safety glasses or goggles.

 

4.3.1        Description:

·         Basic Face Shield: sheet of clear plastic that extend from the eyebrows to below the chin and across the entire width of the head.

·         Welding Shields:

o   Fitted with a filtered lens that has a shade number to denote protection against radiant energy from the arc.

o   Protect the eyes and face from burns caused by ultraviolet light. 

o   Protect the face from flying sparks, metal spatter, and slag chips.

 

4.3.2        When to Use:

·         Basic Face Shield:

o   Work involves flying particles or chemical splashes.

·         Welding Shields:

o   Work involves welding, sparks, or metal spatter.

 

4.4              Safety Shoes:

Footwear constructed to protect the foot and/or toes from injury. 

 

4.4.1        Description:

·         Impact-resistant toes and heat resistant soles. 

·         Various materials for specific hazard issues. As an example:

o   Puncture – Metal insoles

o   Electric Shock – Non-conductive material

o   Static Electricity Buildup – Conductive material

o   Chemical Resistant – Rubber, polyurethane, neoprene, etc.

 

Other types of foot protection that may be required:

·         Metatarsal guards: made of aluminum, steel, fiber, or plastic. They are strapped to the outside of shoes to protect the instep area against impact and compression hazards.

·         Toe guards: made of steel, aluminum, or plastic. They fit over the toes of regular shoes to protect the toes from impact and compression hazards.

·         Combination foot and shin guards protect the lower legs and feet. They may be used with toe guards when additional protection is needed.

 

 

4.4.2        When to Use:

·         Construction areas,

·         Falling or rolling hazards,

·         Penetrating material, or

·         Chemicals. 

 

4.5              Hearing Protection

Devices used to reduce the potential of hearing damage that can be caused by exposure to noise level >85 dBA. The need for hearing protection is determined by the following:

·         How loud the noise is, and

·         The duration of exposure.

 

4.5.1        Description:

·         Earplugs:

o   Inserted into the ears

o   Can be either disposable or reusable. 

·         Earmuffs:

o   Reusable

o   Completely covers the ears.  

4.5.2        When to Use:

·         Work involves noise level ≥ 85 dBA.

 

4.6              Gloves

Protect hands from injury
